Stripped of a Government contract in 2015, Lifeline is trying to rent out office space at its Auckland headquarters to make ends meet.

Each year, Lifeline receives more than 100,000 calls. Last year more than 18,000 had to be dumped due to overloading.

This year more than 7000 calls have been dumped.

'We can't answer every call that comes our way, but if they leave a message, we will always call them back," Ms Schnell said.

When contacted by Newshub, the Minister and Ministry of Health didn't respond to questions about the unanswered calls at Lifeline.

Instead the Ministry said its contract has gone to a new integrated telephone health service called Telehealth.

If you feel you need help dealing with depression or a difficult time in your life, call Lifeline on 0800 543 354 or the Suicide Crisis Helpline on 0508 828 865 (0508 TAUTOKO). Both are available 24/7.
